-PIPE CUTTER.

rApplication filed February 19, 1927. Serial No.-169,489.

This invention relates to an improved tool, commonly referred to as a, pipe cutter, and.

it has more specific reference to one whichV has been constructed with view toward:

facilitating adjustment Iof `the cutters to readily adapt them for cutting pipes of various diameters.

' An objectof the invention'is to gener-allj,7 L improve upon tools of this classghypioviding one of' comparative simplicity and dur` ability, lwherein novel parts are employedv and the parts so associated that 'a practical,

sturdy, aiid'readily mai'iipulated tool is provided. l v

Briefly, the invention has reference to Y a body including a shank having a right angularlyextending jaw at its outer end'1 this jaw being equipped with cutting disks. At the oppositeend ofthe shank is an especially.

constructed part serving as a carrier as for a slidably mountedl frame. normally held in av predetermined position hy a` spring, and it is constructed to cooperate with a` ,pair of slidable thread grips.

y'Thethreaded portion of a rotary handle extends between these grips and is sivivelly connected to a slide Which carries a complemental disk for cooperationwith therfirst .named disk.

The specific details of the invention will` become apparent from the following description and drawing: n

In the accompanying drawing forming a part of this application, and in Awhich like numerals are employed, to designate like parts throughout the saine: y

Referring to the drawingin detail, the

reference character 1 designates a shank aty the outer end of which is a curved right angularly extendingjaiv 2 equipped with suitable cutting disks 3. At the opposite end of the shank is an enlargement, which may be generally designated as a head 1l.,

It will be noted that this enlargement is constructed to accommodate a 'slidable and This frame ybeveled surfaces l13.

gother and it Will lbe' noted from Figs.2 and l that the sections are increased somewhat in-thickness asl indicated at 12, are provided with inclined surfaces 13 andivith cam `r slots 14.Y` VIt is obvious that theV threaded handle 7 extends' ,between these l Inaddition, a gripping device indicated generally at`15 is interposed between Lthebevels and the handle. This kgripping device is vcomposed of tivo grips 1,6 of the construction shown in Each grip'lG has outstanding flanges 1T vhich vstraddle the ,portions 12 of the sections 10. It follows that the port-ion of the grip between the flanges is inclined as atv 18 for cooperation with the complemental bevel 13. Moreover, the grips are provided with semi-circular grooves which are screiv threaded as at 19. Y Vhen Athe two grips are in a predetermined relation, they cooperate with the threaded portion of the handle` so that positivefeed is had. l

The' grips, hoiif'ever, may be disengaged from the threads and this is done by extending pins 2O through the flanges 17 and aforesaid shank 1 andthis carries a cutting disk 25. Then the threaded part of the handle 7 is swivelly connected as atk 26 with its slide.

Under ordinary circumstances, the coiled spring 23 presses the sliding frame 9 preferably to the position indicated in Fig. 2. In so doing, the pin and slot connection releases a cam action which maintains the two thread gripsV 16 in firm engagement with the thread 7 of the handle 5. Thus, a positive feed block is provided, and by turning the hand grip 6 inthe usual way, the slide 24 may be moved back or forth to The feature of the construction is to allow a quick adjustment to be made. it is only necessary to place the palm of the hand against the presser Il and to thrust the fiame 9 down against the action of the coiled spring 23; In so doing, the thread grips 16 are spread apart a distance to be si'diiciently allowed free4 sliding of the handle 5. As soon as the sliding frame is released, the spring moves the frame back up and renders the block effective to resume its action in bringing about the usual threaded movement of 'the'handle It is believed that by considering the description in connection with the drawings, persons familiar with tools of this class will be able to obtain a clear understanding of the saine. Therefore a more lengthy description is thought unnecessary.'

IVhile the preferred embodiment of the invention has been shown and described, it is understood that minor changes coming within the field of invention claimed may be resorted to if desired. Moreover, it is to be stated that while the invention has been restricted more particularly to use and association with a pipe cutting tool, it is not to be limited to'this purpose and use, for it is equally well adapted for use and association with safety jacks, wrenches, and'other parts of machinery requiring quick adjustment.

Having thus described my invention, what I claim as new is l. In a tool of the class described, a shank having a jaw at one end provided with cutting means and having a head at its opposite end, said head being formed with a passage disposed in parallelism with said shank, a handle passing through said pas-, sage, a slide mounted on said shank, a cut-v ter carried by said slide and coopera-tive with the irst named cutting means, said handle being swivelly connected ywith said slide, a frame slidably mounted upon said adjust the cooperating cutting rdisks 3 and- 'Io do this, I

head, a-pair of compleinental relatively'inovable grips associated with the vhead and passage aiid engageable withv said shank, and an operating connection between the frame and the grips, whereby to release the grips to facilitate adjustment of said slides.

2. In a tool of the class described, a shankV having a jaw at one end provided with cutting means and having a grooved head at its opposite end, said head being formed with a passage disposed in'parallelism to said shank, a handle passing s'lidablyfand rotatably through said passage, a 'slidev mounted on said shank, a cutter carried by the slide and vcooperative with theiirst named cutting means, said handle being swive ly connected with said slide, a framey slidabl i mounted in the Grooves on said head and a cam coactiiig means affording operating connections between the shank and said frame. i

.In a structure of the class described, a shank having pipe engagingmeans at one end and a grooved head -atthc Aopposite,

end, a slide mounted on the shank and cooperable with said means, a handle including` a threaded portion swivelly connectedv with said slide, said head having 'an opening through which the threaded portion is operable, a pair of grips mounted'in said head and coopei'able with threaes'on said handle, a spring pressed frame embracing the head and slidable in the grooves on said head, and pin and .slot connections between the frame and said grips.

il. In a structure of the class described, a shank having pipe engaging means atene end and a groovcd head at the opposite end,

a slide mounted on the shank and cooperable with said mean's,a handle including a threaded portion swivelly connected with said slide, said head having an opening through which the threaded portion is oper-V able, a pair of grips mountedv in said head and cooperable with threads on said handle, a spring pressed frame embracing the head and yslidable iii the grooves on said head, pin and slot connections between the frameV and said O'iips, la spiiiig'interposed between tlieffiaine and said head, and ycooperating shoulders on the head and frame for liinit- 'i ing the sliding movement of the frame in y' 11o one direction.

In testimony whereof I. aiiix my signature.v Y
